NIMS |matlab| toolbox

./_pictures/icon_nims.png

The NIMS toolbox has been developed to plot and to analyze (nano)indentation data (obtained with conical indenters) for bulk material or multilayer sample.

With this Matlab toolbox, it is possible to :
  • plot and correct nanoindentation dataset with standard deviation ;
  • calculate the coefficient of the power law fit of the load-displacement curve ;
  • calculate the energy of the loading (area below the load-displacement curve) ;
  • plot of the stiffness and the load/stiffness² evolution ;
  • calculate the Young's modulus and hardness of bulk materials ;
  • calculate the Young's modulus and hardness of thin films on a substrate (for a bilayer or a multilayer sample (until 3 layers on a substrate)) ;
  • generate Python script of axisymmetrical FEM model for use in ABAQUS (cono-spherical indentation of multilayer sample).
